I am now an older mountain biker and sad to say I no longer weigh 138 pounds, I have gained some weight. I am 60 years old 5'7" tall and now 145lb. I had a cycling rain jacket by O2 Rainwear just a cheap one I bought from Amazon years ago and it worked great, but now that I have gained some weight it is really tight in the waist and I know that I would not be able to zip it if I wanted to layer with some heavy clothes for winter riding. I have had the same issue with a Specialized and Pearl Izumi jackets. The Showers Pass jacked fits me like a normal jacket in the waist and there is still room to layer with heavier clothing under it, it feels comfortable to wear. I have not had a chance to use this in any rain but from reading other reviews I don't think that will be a problem. I also follow a YouTube’er Ryan Van Dusser who does bike packing and he wears a Showers Pass jacket in several of his videos but I do not know if it is the same model but it seems to work really well for him. The build quality looks good to me, the fit is great and I have a size small, I like the color (Firecracker Red) and the price was great. It fits in my hydration pack well and since I am in Arizona I can't wait to try it out, no there is no such thing as too much rain in AZ. I believe this jacket is going to work really good for me for several years.
